Re: [Freeipmi-users] possible causes for "ipmi_ctx_open_outofband: BMC busy"

[Werner Fischer]

Hi Al,

thanks for this info.
I now got the info that this user is using FreeIPMI only for Nagios, but
is using ipmitool for his cacti monitoring. I assume that he does not
use the SDR cache function of ipmitool, as it has to be used manually
and that this is the root cause.

I told him to use "ipmitool sdr dump" and then "ipmitool -S" - I think
this will solve his problem.

Thanks for your help,
Werner
